For centuries, parts of the valuable moss area were given to the locals to use. The rights of use were allocated by lot. From the middle of the 19th century until 1971, this lottery took place every ten years at the Ramsach Church of St. George - always on Whit Tuesday. The small church is called Ähndl' by locals - "the ancestor of all churches". The use and care of the portion of the moss allocated by lot usually included grazing rights and the production of bedding for stables through the so-called "bedding mowing". The reeds are mown every two to three years in late summer, dried and then stacked into the typical "strawdrisches". These characteristic straw piles were also used as a motif by the artists of the "Blue Rider". If the ground was hard enough or frozen, it was transported away by ox cart. Any bedding left over from the farm's own livestock farming could be sold. The same applied to the cut peat extracted from the moor, which, however, was often only used for domestic needs due to a lack of quantity and quality. The nearby quarry on the Moosberg, which had already been used in Roman times, brought in greater yields. At the beginning of the 19th century, it received a new boost when cheap material was needed in Munich for the gravel underlayment of the new road paving. The stones were transported to Munich on the Loisach and the Isar. The industrial rock mining on the Köcheln in the moor from 1925 onwards caused deep cuts in the landscape as part of a state job creation programme to promote the economy by the "Hartensteinwerk Moosberg". From 1930 onwards, mining began on the "Langen Köchel" near Eschenlohe by the private quarry company "Hartsteinwerk Werdenfels GmbH". The rock mining did not even stop at a Roman settlement: its remains hindered the rock extraction. It was completely destroyed between 1925 and 1934. An emergency archaeological excavation before the explosions made it possible to document and secure the finds. Under National Socialist rule, railway and road construction led to an increased need for gravel. The plant near Eschenlohe also supplied large quantities of building material for this. The Murnauer Moos, a relic of the last ice age and the Loisach glacier, is unique due to its size and diversity. Rock mining, drainage and use were always accompanied by demands for careful interventions in nature. It is thanks in particular to the intensive efforts of Ingeborg Haeckel, the granddaughter of the famous biologist Ernst Haeckel, that the Murnauer Moos with its great biodiversity is now classified as worthy of protection and is placed under nature conservation.
